I made a cheese taco shell a while ago and it was delicious! Make a large Cheese Chip (from recipe section) and to make the bend in the 'shell', I suspended a wooden spoon between 2 tall cans and as soon as I took the cheese out of the microwave I draped it across the spoon. It hardens as it cools. I stuffed it with all the traditional fillings and it was great. One was enough for me.

another idea would be toasting an LC tortilla wrap until crispy (either bend it over something bake-proof or else break it up and use it as chips) or make the Cheese Chips and use those to scoop the filling or have on the side with your taco salad??

Oh, BTW, I use parchment paper when I make the cheese chips in the microwave. Doesn't stick and I just blot them with paper towel while they're still hot.
